Q1: What is the typical purity level of Oxygen produced by Small Cryogenic Air Separation Units?
A1: Across all models in the KDON series (from KDON-50/50 to KDON-550/1000), the Oxygen (O₂) purity level consistently reaches ≥99.6%.
Q2: How pure is the nitrogen output from the High-Purity Nitrogen Units?
A2: The High-Purity Nitrogen Units (KDN series) deliver nitrogen with an extremely low oxygen content of ≤3 ppm O₂, ensuring optimal performance for highly demanding applications.
Q3: Can the Liquid Cryogenic Unit produce Liquid Argon, and what is its purity?
A3: Yes, the KDONAr-1300y/200y/40y model is capable of producing Liquid Argon (LAr) at an output rate of 40 Nm³/h with a purity level of ≤1.5ppm O₂ + 4ppm N₂.
Q4: What is the main composition of atmospheric air by volume fraction?
A4: Atmospheric air is primarily composed of Nitrogen (N₂) at 78.084%, Oxygen (O₂) at 20.95%, and Argon (Ar) at 0.932% by volume fraction, with other trace elements making up the remainder.
Q5: What are the boiling points of the primary components of air?
A5: Under standard conditions, Nitrogen (N₂) has a boiling point of -195.8 ℃, Oxygen (O₂) has a boiling point of -183 ℃, and Argon (Ar) has a boiling point of -185.7 ℃.
Q6: How does the unit energy consumption change with larger Air Separation Units?
A6: As the capacity of the unit increases, the energy efficiency improves. The unit energy consumption drops from ≤1.3 KWh/Nm³O₂ for the KDON-50/50 model down to ≤0.65 KWh/Nm³O₂ for larger models like the KDON-550/1000.
